So, if you’re a Xiaomi device user and want to get an early taste of Android 11 on the top of MIUI 12, then you may have to wait for Chinese developer beta update. Most of the developer beta updates released for the Xiaomi devices always roll-out in China first. Then the global developer beta update releases. Once the company ensures that the beta update is now almost bug-free and can be served as a stable one, Xiaomi starts rolling out the official stable update in batches. Though the development process, bug fixes, and official stable update releases from Xiaomi are quite slow than some other popular OEMs, we can expect that the company will try to improve their update timeline frequency.
Currently, the interested Xiaomi users can’t apply for the MIUI 12 beta testing program as they’re getting error notice. It seems that Xiaomi is working hard on it and the beta testing recruitment process will start very soon for a couple of specific device models in its initial stages. Then maybe the device model counts become higher as the development process becomes quite normal. A member from Mi Play device team has confirmed that the Xiaomi Mi Plau will be getting the MIUI 12 update and the work on MIUI 12 has already started.
As of now, due to the COVID-19 pandemic disease, the development process or recruitment process may be delayed. Meanwhile, if you want to know the exclusive features of Android 11, then check the details here. Source
